## Homework Statement

A quarterback throws a football with an initial speed of 19.0 m/s at an angle 30.5deg above the horizontal. Unfortunately, the pass is incomplete and the football drops to the ground, 35.0 m away from the quaterback. From what height was the football released? (no diagram provided)

## Homework Equations

Vy= Vknoty - gt from which we get t

_{tot}= [tex]\frac{2V

_{o}sin\vartheta}{g}[/tex]

from the equation y= V

_{oy}t

_{y2}-0.5gt

_{0.5}

^{2}we get hmax= v

_{0}

^{2}sin

^{2}g[tex]\vartheta[/tex]/2g

## The Attempt at a Solution

so to figure out far it goes i used the equation xmax= v

_{0x}t

_{tot}where it wld now equal vknotcos[tex]\vartheta[/tex](2*vknot sin[tex]\vartheta[/tex]/g) + distance it travelled and i wanted to know what i was doing wrong thanx
